Abstract. This paper reports the effects of elevated pressures on the crystal structure of potassium dinitramide â an energetic material that is a precursor for ammonium dinitramide and which has been considered as an oxidiser in its own right. The smooth variation in unit-cell parameters provided no evidence for a phase transition up to ~10.5 GPa. The variation in unit-cell volume was fitted to a 3rd order Birch-Murnaghan equation of state.
Keywords: KDN; high pressures; phase transition; single-crystal X-ray crystallography
